Set 10: Exponential Functions
Explanation
Which table of values represents an exponential function?
(0, 2), (1, 4), (2, 6), (3, 8)
(0, 2), (1, 4), (2, 8), (3, 16)
(0, 2), (1, 3), (2, 5), (3, 8)
(0, 10), (1, 9), (2, 8), (3, 7)
Detailed Explanation
Choice B is correct. Choice B is the correct answer. Exponential functions have a constant ratio between consecutive terms. 1. Check A: . Constant difference (Linear). 2. Check B: . Constant ratio (Exponential). 3. Check C: . Not constant. 4. Check D: . Constant difference (Linear). Strategic Tip: Additive pattern = Linear. Multiplicative pattern = Exponential. Choice A is incorrect because it adds 2 each time. Choice D is incorrect because it subtracts 1 each time.
Key Steps:
The correct answer is (0, 2), (1, 4), (2, 8), (3, 16)
